SELF-*CLOSING SAFETY-FILLING CAP.

Application filed May 27, 1926. Serial No. 112,174.

This invention relatesv to al novel cap for liquid'containers such as oil cups, autoincbile radiators, crank cases and gasoline storage tanks, and the like, and has forone of its objects to provide a device of this char-y acter which will prevent the entrance otx dust and other foreignniatter into the container,

' which to permit the container to be tilled, may be readily opened through the medium or' the spout ot an oil can or water bucket .or the nozzle of the filling hose ot a gasoline dispensing station and the like, and which will automatically close immediately after the withdrawal of the spout or nozzle. With the foregoing and other objects in View, the nature ot'` which will become apparent as the description proceeds, the invention consists of the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:

' Figure 1 is a sectional view taken on a plane extending fvertically and centrally through the cap,

Figure 2 is a sectional view taken on the vertical Aplane indicated by the line 2 2 of Figure 1,

j Figure 3 is a sectional View taken on the horizontal plane indicated by the line 3-3 of Figure 1, and j Figure 4 is a similar View taken on the horizontal plane indicated by the line 4--4 `cfa-Figure 1.

Corresponding and like parts are referred to in the following description, and designated in the several viewsl oi the accom! panying drawng, by similar reference characters.

The cap comprises a hollow cylindrical body 1 which is closed at its upper. and fully open at its lower end. The body 1 is provided at its lower end with a laterally offset and internally screwthreaded iange.

2 to permit of its attachment to an yoil'cup, automobile radiator, autoinobile'crank case, automobile gasoline storage tank or the like. The oii'setting of the iiangc 2 from the body 1 provides a horizontal shoulder 3. The top 4 of the body 1 extends laterallybeyond the latter, and is provided with Y an upwardly and laterally extending lprojection or lip 5 which has a concave under face G. A iilling opening 7 which extends vertically and longitudinally thereof, is formed in the body 1 immediately below the vextension (l.

The vert-ical dimension oil the opening is less than the corresponding dimension of t-he body;1, and such opening is located in the upper portion of the body. A hollow cylindrical valve 8 which is open at its upper and closed at its lower end, is slidably arranged within the body 1, and is adapted to occupy a closed oran opened position with respect to the body. When the valve 8 is in closed position, it extends over the lilling opening 7, and a flange 9 projecting from its bottoni 1.() is in contact with the under side or' the shoulder vWhen the valve 8 is in opened position, the iilling opening? is uncovered and the flange 9 is spaced below the shoulder The ,valve 8 is yieldingly re tained in closed position by a` spring 11 which is mounted upon a rod 12 between a seat 13 bearing against the under side of the bottoni 10 of the Yvalve and a seat 14 resting upon a nut 15 adjustable. on the rod. lhe rod 12 is secured to and depends :troni a bar 16 which is arranged within and extends diametrically of the body 1 and valve 8 and is secured as at 17 to the body. The upper end of the rod 12 passes through the bar 16 and is secured to said bar by nuts 18 carriedkv by the rod and contacting with the upper and lower sides of the bar. The bottoni 10 ot the valve 8 is provided with an opening 19 tor the reception of the rod 12, and the lateral side of the valve 8 is provided witn longitudinally and vertically extending slots 20 for the reception of the ends ot the bar 16.- The seats 13 and 14 are loose on the rod 12, and the nut15 may be Vadj usted to vary the tension or the spring 11. The lateral side of thevalve 8 is provided with ports 21 through which the liquid iows into the container when the valve 8 is in opened position and which are located wholly within and closed by the body 1 when the valve is in closed position. A A sleeve 22 surrounds the body 1 and is secured to the valve 8' by a screw 23. The axial dimension of the sleeve 22 is less than the corresponding dimension of the valve 8 and body 1, and said sleeve is adapted5 when the valve is closed, to occupy a position upon the uppery portion 'or' the'body 1 over the tilling opening 7.

The screw 23 passes through the lling opening 7. The sleeve 22 is provided directly below the extension 5 with an upwardly and laterally projecting extension 24 which is provided with a concave upper face 25 and with openings 26. The extension 24 provides an element through the medium of which ille vulve 5l muy be reo'flily dolflreseiod oi.' moved ioio opened poeiiioo, mid ibo opere ingo ilo ore provided lor ibo porpoee oli Meinl-:doing tbe upper .migliore ol :fold eleoieol's :free of moisture.
